Requests to the Contacts API require proper authorization. Use OAuth 2.0 with the GHL app credentials and the scope essentials such as contacts.readonly. Store tokens securely and rotate them regularly.
Active Knocker authenticates via the same token or OAuth flow configured in your GHL developer settings to access the Contacts API endpoints securely.
GET /contacts/:contactId GET /contacts/:contactId/tasks GET /contacts/:contactId/tasks/:taskId GET /contacts/:contactId/notes GET /contacts/:contactId/notes/:id GET /contacts/:contactId/appointments GET /contacts/ GET /contacts/business/:businessId POST /contacts/ PUT /contacts/:contactId DELETE /contacts/:contactId POST /contacts/:contactId/tasks PUT /contacts/:contactId/tasks/:taskId PUT /contacts/:contactId/tasks/:taskId/completed DELETE /contacts/:contactId/tasks/:taskId POST /contacts/:contactId/tags
Trigger when a contact is updated in GHL to keep Active Knocker in sync.
Actions: mirror contact changes, sync associated tasks and notes.
GET /contacts/:contactId
Key fields: contactId, email, name
Trigger: new tasks created in GHL triggers a new task in Active Knocker
Actions: propagate task details and due dates to Active Knocker
POST /contacts/:contactId/tasks
Key fields: contactId, taskId, status
Trigger: an appointment is created in Contacts API
Actions: create reminders and calendar events in Active Knocker
POST /contacts/:contactId/appointments
Key fields: contactId, appointmentId, time

Real-time data sync and streamlined workflows
A quick glossary of terms used in this guide and the core processes for building GHL API connections between Contacts API and Active Knocker
Application Programming Interface: a set of rules that lets applications talk to each other.
Authorization framework enabling secure access to APIs without exposing credentials.
A callback URL that notifies your system when events happen in another app.
A URL path that performs an action or returns data in an API.
Capture form submissions via GHL and automatically create or update contacts in Active Knocker.
Automatically assign tasks to teams when a contact is updated in GHL.
Trigger appointment reminders in Active Knocker when a new contact appointment is created.
Create an API key or OAuth client in GHL and grant the Contacts API scope.
Enter the endpoint paths and field mappings from the Contacts API into Active Knocker.
Run test requests, verify data sync, and enable live automation.
No coding is required thanks to the no-code integration surfaces provided by the GHL API. You can map fields and set triggers without writing code. If you need custom logic, you can use webhooks or small scripts within your automation platform.
Core syncing typically involves reading contacts, retrieving tasks, notes, and appointments, and creating/updating contacts as needed. The essential endpoints are GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and POST /contacts/ to create new records.
Use OAuth 2.0 with client IDs and secrets, or API keys with scoped access. Ensure tokens are stored securely and rotated regularly.
Yes. You can adjust field mappings in the Active Knocker setup, aligning GHL contact fields to your app fields, and you can use transformation rules.
Sync frequency can be real-time with webhooks or scheduled at intervals (e.g., every 5, 15, or 30 minutes) depending on your plan and needs.
Yes. Webhooks deliver events as they occur. You configure endpoints in GHL and Active Knocker to receive and process these events.
You can view logs in the integration dashboard, including requests, responses, and error messages, to diagnose issues.
Due to high volume, we will be upgrading our server soon!
